I dont know about that brand, but all of my Snap On ones just go back to Snap On. I had a Mac 3/8, but my Snap On guy said they wouldn't do other brands, so I traded it in and got a Snap On.

I would suggest trying to get a hold of Husky, and see if they do it, or find some independent place. I would think it wont be worth having those re-calibrated, it might be cheaper to just buy new ones.

I know it isn't the correct way but i check mine every so often with a friends that i know is calibrated since he is a mechanic. I put mine in a bench vice with an Allen wrench socket in it and take my friends with the appropriate standard socket that will fit the Allen wrench. Set them to the same torque and see if the break loose at the same time. It at least tells me if they still work. I have never had one be off enough to mess with.

like chad said. as long as they dont sit in the box with all the tension on them im sure they are still good enough for what youd be doing. just make sure to take all the tension out of them when your done and they will last for a long time.

Well, after a quick google search I found half a dozen places around the Detroit area that calibrates torque wrenches. My last employer required all precision eqmt, torque wrenches, micrometers, dial indicators, etc., to be calibrated annually and to be calibrated for new hires before they could use them on eqmt. All of my eqmt was calibrated, tagged, and had a digital file to be attached to repair orders when they were used in the repair.
